Hello everyone! I have a question about module development. I am working with a tool that produces a compressed VCF file (.vcf.gz) but does not create a tabix index. The tool is available from Bioconda, and I am currently using the corresponding biocontainers image. However, the container/environment for this tool does not include tabix. What would be the recommended nf-core approach here? 1. use a mulled container / add htslib to the Conda environment and run tabix after the tool, or 2. skip tabix indexing entirely and leave indexing to a downstream module or pipeline step?

I would go for 2. because we have a tabix module which can do that downstream if the index is really needed. Sometimes the index is not neeeded.

Thank you for reply

note that making "mulled" containers is so much easier given that we have Seqera containers available
